我国典型超高层建筑的抗震韧性评价研究
Research on seismic resilience assessment of typical super-high-rise buildings in China
摘要
Abstract
During China's rapid urbanization process,the height and quantity of super-high-rise buildings have developed significantly.Their seismic resilience has become a focus of attention.This paper,considering the deformation characteristics and structural system composition of super-high-rise buildings,improved the seismic resilience assessment method of the GB/T 38591-2020'Standard for seismic resilience assessment of buildings'(hereinafter referred to as the Standard),including the use of harmful displacement angle as engineering demand parameter to assess the damage state of shear wall components in the core tube,the establishment of a test database for steel-concrete composite components,and the training of a machine learning model for predicting the vulnerability parameters of composite components.The seismic resilience of 12 typical super-high-rise buildings from different regions,with different heights and seismic intensities,was evaluated.The overall level of seismic resilience of super-high-rise buildings designed according to current specifications and approved through performance-based review were revealed,and the main influencing factors were analyzed.It is shown that the super-high-rise buildings designed according to current specifications generally have good seismic resilience,and buildings located in high-intensity zones are faced with greater challenges to achieve seismic resilience.Based on the evaluated cases,the limit values for comprehensive economic indices corresponding to the grading system of the Standard were proposed,and the implementation pathways for the seismic resilience of super-high-rise buildings are discussed,to provide references for the seismic resilience design and improvement of future high-rise and super-high-rise buildings.关键词
